The beveled upper surfaces 21 of the teeth 19 enable the teeth to readily enetrateV the section 1 of the tubing an the coupling 3 so as to properly perform the cutting function. After the severed tubing has been removed, the device is Withdrawn the beveled upper portions 24; of the hooked ends 13 of the hangers 12' allow for the ready passing of the hooked ends ot' the hangers 12 by the lower edge 25 of the scction 1. The device is removed by elevating the bar 5 through the medium ot' the rod 7 so that the nuts 9 will engage the annular member 10.
